If you're using the Razorback and just standing still, you're doing it wrong. I find it's best used with the Huntsman, because Huntsman Snipers are always moving around, so they're harder to hit with the Revolver. There's a reason those two weapons were released in the same update.

I suggested several on the youtube weapon demonstration-Recharges after about 10 seconds (not very effective in 1 spy attack)-Make it invisible untill a spy backstabs them (makes spies have to think a bit)-Grants minicrits to the wearers melee for a few seconds on backstab to help them defend themselves-Apon being attacked by a spy grants 2 seconds of immunity allowing retalliation

+ Blocks oncoming backstab, stunning the spy.+ Upon blocking a backstab, causes user to get crits, and get a speed boost (Like the Soldier's Disiplinary Action).- Causes Sniper to move slightly slower while wearing (As it was originally meant too)- Upon being backstab, razorback is destroyed, and requires Large Ammo Crate/Respawn Locker to come back.
